Ai Summary

Strengthen security before peak trading: Review WAF rules, bot protection, rate limits and API security to protect against malicious traffic, fraud and potential cyberattacks.

Test performance and checkout under pressure: Simulate realistic traffic surges, test the full purchasing journey and monitor Core Web Vitals to ensure customers can complete purchases during peak demand.

Validate platforms and integrations: Check platform-specific settings across SFCC, Shopify Plus and headless commerce, alongside payment gateways, inventory, tax and fraud services.

Monitor revenue-critical metrics and prepare for incidents: Track checkout completion, payment failures, errors, bot activity and API performance, with clear escalation procedures, recovery plans and 24/7 support.

Maintain readiness throughout Christmas trading: Continue monitoring security, mobile performance, stock availability and payment processing beyond Black Friday and Cyber Monday, through December's peak sales period.

£3.8 billion. That's how much UK shoppers spent online during Cyber Weekend 2025, according to Adobe. Black Friday alone generated £1.16 billion.

But the opportunity comes with a growing risk.

New Accertify research, published in September 2026, analysed 576 million transactions across five Cyber Week seasons. It found that 14% of attempted fraud occurred during an overnight window accounting for just 8% of transaction volume.

And October brought another warning. Cyber incidents involving high profile retailers such as ASOS highlight how quickly disruption to connected retail systems can affect businesses before peak trading even begins.

With Black Friday on 27 November 2026, retailers have less than four weeks to check their defences, test checkout performance and prepare for the unexpected.

Your Eight-Point Ecommerce BFCM Readiness Checklist

Preparing an ecommerce site for peak season means testing the complete purchasing journey, protecting customer-facing systems, checking third-party dependencies and ensuring someone can respond when problems arise.

1. Protect Your Storefront Before Attackers Find a Gap

Malicious bots don't stop at your homepage. They target logins, promotions, inventory, checkout and commerce APIs.

Review Web Application Firewall (WAF) rules, bot mitigation, rate limits and suspicious traffic patterns.

For Salesforce Commerce Cloud (SFCC), include OCAPI and SCAPI endpoints. Test security rules to ensure genuine shoppers aren't accidentally blocked.

TCTG's Managed WAF for SFCC provides real-time threat visibility, automated IP blocking and 24/7 response. Our industry leading solution is helping global retailers save millions in lost revenue.  

2. Test What Happens When Traffic Surges

A successful homepage load test doesn't prove checkout will survive Black Friday.

Simulate realistic customer journeys, including product search, promotions, add-to-cart and payment authorisation.

Test sudden traffic spikes as well as sustained demand. Monitor response times, error rates and failed transactions.

The important measure isn't how many visitors your site accepts. It's how many can still complete their purchase.

3. Know Your Storefront's Performance Limits

Google recommends the following Core Web Vitals thresholds:

Measure real-user performance at the 75th percentile. Use laboratory testing, including Total Blocking Time (TBT), to investigate bottlenecks. Pay particular attention to mobile product pages and checkout.

4. Check Your Platform's Peak-Season Settings

Salesforce Commerce Cloud: Review Business Manager jobs, search indexing, caching, replication schedules and eCDN security. Check relevant API protections before code freeze.

Shopify Plus: Validate themes, discount combinations, checkout customisations, apps and inventory synchronisation.

Headless commerce: Test API response times, CDN behaviour, authentication and fallback handling.

Prioritise essential fixes over last-minute architectural changes.

5. Find the Weakest Link in Your Integrations

Your storefront may be ready while a connected service isn't.

Test payment gateways, tax engines, inventory services, fraud screening and search providers.

What happens when an API times out? Can shoppers continue if a non-essential service fails? Could a retry create a duplicate order?

Agree on escalation contacts and fallback procedures before peak trading begins.

6. Monitor the Metrics That Protect Revenue

Website uptime alone won't reveal a broken checkout or rejected payments.

Your peak trading dashboard should track:

  • Checkout completion and payment failures
  • Cart, search and API errors
  • Page response times and failed jobs
  • Bot activity and WAF events
  • Unexpected changes in order volume

Set alerts against normal trading patterns, with clear ownership.

TCTG Monitoring provides SFCC-specific visibility into performance, jobs, errors and integrations.

7. Know Who Responds When Something Breaks

If payment failures rise at midnight, who's responsible?

Agree on incident severity, escalation contacts, communication procedures and rollback plans.

Rehearse recovery from failed deployments, incorrect configurations and third-party outages.

A monitoring alert is only useful when someone can act on it. That's where 24/7 ecommerce managed support becomes critical.

8. Don't Forget Christmas Trading

Cyber Monday isn't the end of peak season.

Adobe reported that 61.5% of UK online spending during November and December 2025 came through mobile devices.

Keep checking mobile performance, stock availability, delivery cut-offs, payment processing and returns throughout December.

Security monitoring shouldn't stop when the Black Friday promotions finish.
